<p>#CMT# #/CMT# The optical sensor (100) has test detector mounted on rotor (40) rotated along the rotation axis, which is arranged in inner surface of the sensor. The test detector is oriented towards regions of partitioning screen (66) through which the emergent light pulses and reflected light pulses pass. A test light source (54) supplying emergent light pulses, is mounted on the rotor. A reflector element (80) to which the test light is directed, is arranged outside housing (60). The test light reflected by reflector element is detected from the test detector. #CMT#USE : #/CMT# Optical sensor mounted on bridge, for determining contour of vehicle such as forklift truck. #CMT#ADVANTAGE : #/CMT# The partitioning screen can be tested effectively, damage and contamination of the reflector element can be prevented since the reflector is arranged outside the housing, size of optical sensor is reduced since both the light source and the detector can be arranged on the rotor and mechanical impact on the rotor can be reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the optical sensor. 40 : Rotor 54 : Test light source 60 : Housing 66 : Partitioning screen 80 : Reflector element 100 : Optical sensor.</p> |
